RODERICK w. BRYANT; or oMg nA, NEBRASKA DOUBLE SLOPE IR E-RAILING FROGApplication filed November 14, 1928. Serial No. 319,243.

The invention relates to rerailing block s; Patent No: 1,681,2811issuedadapted to be used for replacing the wheels of locomotives and railwaycars upon tracksafter derailment thereof, and has for its ob:

the'invention resides in the combination and 5 ect to provide blockshaving channeled members adapted to arch the treads of rails, providedwith upwardly flange engaging surfaces terminating adja cent the innersides of the rails, whereby the wheel flanges will be positioned whereupon further movement of the Wheels, the wheel treads will engage therail treads and the wheel flanges will engage the rails.

A further object is with apertured lugs for the reception of i spikesfor securing the blocksacross ties and i the under sides of the blockswith lugs adapt ed to imbed in the ties for preventing lateraldisplacement of the blocks.

A further object is to proportionthe inner sides of the rail archingmembers, whereby said inner sides will rest uponthebases oi the. railsfor rigidly supporting the rail sides of the blocks and reducing thestrain on the rail arching members.

A further object is v sides of the block with flattened portions onwhich the wheel flanges rest when they reach 30 the point of re-railmentand'to provide the central portions ot-the blocks with shouldersadjacent the flattened portions which, upon movement of the wheels ineither direction,

will prevent the wheels from going down either incline no matter fromwhich side of 'the'block the wheels have beenelevated to re-railm'entposition.

. A further object is to provide re-railing blocks mounted adjacentrails and having upand inwardly extending wheel .re-

moved to re-railing positions from either end of the blocks withoutchanging the blocks,

thereby obviating the" necessity of providing instance the type aplurality of blocks, for

and I inclined wheel the inner sides of to provide the blocksv attheleft hand side of Figure shown in Figure 8.

to provide the upper above and other arrangement of parts as hereinafterset forth, shown claimed, it being understood that changesin in thedrawings, describedand the precise embodiment'of the invention may bemade within the scope of what is claimed without departing from thespirit of the invention. ,r

Disposed adjacent the nails 1 are re-railing blocks 4 and 5,,which blocks have their under sides provided;withjdownwardly extendingsharpened lugs 6 adaptedto imbed v I in'the' cross ties for preventinglateral'movement of the blocks when in'vposition-if The blocks areadditionally held against displacement by :nieansof Y spikes 7 whichextend,

through apertured' lugs 8' and into the cross ties. Block}; ls placedtothe outside of one top plan view of a section of of the rails and block5 to the inside of the other rail.

The blocks 4 and 5 are provided at one side thereof with invertedchanneled members 9 which arch the treads of the rails and onto whichthe wheel flanges are guided by means hereinafter set forth. The blocks4 and 5 at their sides adjacent the rails engage the rail bases 10 forrelieving the strain on the channeled members when the weight of anengine or car is on the blocks.

Referring specifically to. the block 4, the opposite ends of said blockincline downwardly from the central flat portion 11 and are providedwith downwardly inclined flared channels 12 onto which the wheel flangesare forced from either side of the block. As the wheel flanges moveupwardly they engage the shoulder 13 of the block and are guidedinwardly onto the channel 9, which is a fiat surface, and into aposition where as the wheel rotates, it will move to a position inengagement with the rail 1 and with its flange engaging the inner sideof the rail.

The block 5 is provided with downwardly inclined flared channels 14:into which the wheel rolls according to the direction of movement of thewheel and. the wheel is guided toward the adjacent rail lby engagement,

with the flanges 15, and when the wheel reaches the central position,the wheel flange will engage the webs 16 or" the blocks and will be in aposition where upon movement of the wheel in either direction the treadof the wheel will engage the tread of the rail 1 and the flange of thewheel will engage the inner side of the rail. It will be noted that byproviding double ended re-railing blocks, only two blocks will benecessary, and the wheels may be placed on the rails by moving the samein either direction.

From the above it will be seen that re-railing blocks are provided,which may be used for re-railing rolling stock wheels moving in eitherdirection, thereby obviating right and left hand blocks of the singletype now in use wherein it will require four blocks. It will also beseen that the side of each block is provided with a channeled memberarching the rail in engagement therewith, and that the inner lower edgeof the block rests on the rail base thereby positively bracingthe blockand relieving the strain 'on the channeled member. v

The invention having been set forth what is claimedas new and useful isA double slope re-railing block comprising an elongated body memberadapted to be dis posed to one side of a rail in engagement therewith,an outward and downwardly eX- tending member car ied by the body memberand adapted to arch the tread of a rail, upwardly inclined recessescarried by the ends of the body member, whereby wheel flange signature.
